Abstract

A variable optical attenuator (VOA) is a crucial component for optical communication, especially for a variable multiplexer (VMUX) and reconfigurable optical add-drop multiplexer (ROADM). With the capacity increasing dramatically, a large-port-count and low-power-consumption VOA array is urgent for an on-chip system. In this paper, we experimentally demonstrate a 16-channel VOA array based on a polymer/silica hybrid waveguide. The proposed array is able to work over C and L bands. The VOA array shows an average attenuation larger than 14.38 dB with a low power consumption of 15.53 mW. The low power consumption makes it possible to integrate silica-based passive devices with a large port count on-chip.

基于聚合物/二氧化硅混合波导的低功耗、宽带 16 通道可变光衰减器阵列

可变光衰减器（VOA）是光通信的关键部件，尤其是可变多路复用器（VMUX）和可重构光分插多路复用器（ROADM）。随着容量的急剧增加，大端口数、低功耗的 VOA 阵列对于片上系统来说已迫在眉睫。在本文中，我们通过实验演示了基于聚合物/二氧化硅混合波导的 16 通道 VOA 阵列。所提出的阵列能够在 C 和 L 波段工作。VOA 阵列的平均衰减大于 14.38 dB，功耗低至 15.53 mW。低功耗使得在芯片上集成具有大量端口的硅基无源器件成为可能。

期刊介绍： Photonics (ISSN 2304-6732) aims at a fast turn around time for peer-reviewing manuscripts and producing accepted articles. The online-only and open access nature of the journal will allow for a speedy and wide circulation of your research as well as review articles. We aim at establishing Photonics as a leading venue for publishing high impact fundamental research but also applications of optics and photonics. The journal particularly welcomes both theoretical (simulation) and experimental research. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
